Magnetic attachment The strong magnet securely attaches to metal surfaces, enabling hands measurement and enhanced stability and accuracy during readings. Dual measurement modes Offers both relative and absolute measurement modes, allowing you to track changes from a reference or read direct, absolute values. Suitable for a range of tasks including angle measurement and slope checking. Angle and slope conversion Easily switch between angle measurements and slope percentages to match your drawings and specifications. This versatility supports construction and carpentry tasks that require different formats. Data lock function Data lock freezes the displayed measurement for easy reading and eliminates the need to manually record readings while you work. Use scenarios Construction and carpentry: verify framing angles, check roof pitches or stair slopes, and align components on metal surfaces without handling the tool directly. Metal fabrication and mounting: align brackets and machine parts, confirm precise angles during assembly, and ensure components sit at the correct slope. Cabinetry and interior finishing: install shelves or fixtures on metal walls with accurate angle or slope readings, reducing rework and measurement errors.
